# B1 Dust Class Safety Vacuum Cleaner \u2013 For Explosive Atmospheres<\/p>\n
This detailed product description presents the technical features and advantages of the Wiel\u00e4nder+Schill B1 Class H safety vacuum cleaner (Item No.: 932464), highlighting its suitability for safe application in explosion-hazard areas.<\/p>\n
## Overview and Key Features<\/p>\n
The B1 dust class safety vacuum cleaner has been specially developed for use in **Zone 22 hazardous areas**, meeting the strict requirements of the B1 dust class. This device is critically important in work environments where the presence of dust can pose an explosion hazard. For safe operation, the vacuum cleaner is equipped with an **antistatic suction hose (3.5 m)** and built-in **AntiStatic technology**, which effectively minimizes the risk of electrostatic charge when vacuuming hazardous and explosive dusts.<\/p>\n
For maximum flexibility and functionality, the device comes with a rich set of accessories, including a tool adapter, filter element, and filter bag. Particularly outstanding is the length of the **7.5-meter rubber mains cable**, which ensures convenient positioning and mobility even over large work areas.<\/p>\n
The vacuum cleaner can be further extended as it is **connectable to eccentric sanders**, significantly increasing the spectrum of application areas, making it ideal for demanding and safety-critical workplaces.<\/p>\n

## Detailed Functions and Advantages<\/p>\n
### Explosion Protection and Safety (ATEX Compliance)<\/p>\n
The most important advantage of the device is its safe use in potentially explosive environments. The **Zone 22** marking guarantees that the vacuum cleaner complies with European ATEX directives (II3D category), meaning it is suitable for collecting dust in areas where explosive dusts occur rarely, and if they do, will not cause an ignition source.<\/p>\n
* **AntiStatic Technology:** This special design prevents the discharge of static electricity generated in the suction system, which can be the most common ignition source in the case of explosive dusts.
\n* **Antistatic Suction Hose:** The 3.5-meter hose does not conduct electrical charge, further increasing the safety level.<\/p>\n
### Performance and Efficiency<\/p>\n
The 1500 W motor and the 3800 l\/minute volumetric flow rate ensure that even finer, B1 category dust can be efficiently and quickly vacuumed. The 70 liter tank capacity reduces the need for frequent emptying, thereby increasing workflow continuity.<\/p>\n
* **Large Work Area Coverage:** The 7.5-meter rubber mains cable allows the vacuum cleaner to be positioned without the user having to constantly relocate the power source.
\n* **Strong Vacuum:** The maximum negative pressure of -250 mbar guarantees sustained suction power even if the filter is partially loaded.<\/p>\n
### Flexibility and Expandability<\/p>\n
The vacuum cleaner is suitable not only for basic extraction but can also be integrated into more complex systems:<\/p>\n
* **Connection of Orbital Sanders:** The included tool adapter enables direct connection to certain sanding tools, allowing dust to be immediately extracted at the source, improving air quality and work precision.
\n* **Accessories:** The filter element and filter bag ensure proper filtering and containment of dust, protecting the motor and the environment.<\/p>\n
### Design and Durability<\/p>\n
The device is made from durable materials such as plastic, stainless steel, and steel, ensuring a long service life even in harsh industrial environments. Despite the weight of 25 kg and the robust design, the vacuum cleaner is easily movable within the work area. The 59 dB(A) noise level contributes to a more pleasant working environment.<\/p>\n
This safety vacuum cleaner is the ideal choice for automotive workshops, paint shops, and any industrial area where there is a risk of dust explosion and where reliable, high-performance extraction is required.<\/p>","protected":false},"excerpt":{"rendered":"
